Final answer:
Option A). Your motherboard must have a TPM chip to use BitLocker Encryption in Windows 7 and prevent your hard drive from being used in another computer.
Step-by-step explanation:
You need a TPM (Trusted Platform Module) chip on your motherboard in order to use BitLocker Encryption in Windows 7 and guarantee that your hard drive cannot be used in another computer.
A hardware element that offers safe storage for encryption keys is called a TPM chip. It protects the hard drive from unwanted access by encrypting it and cooperating with BitLocker.
BitLocker is not directly related to the use of a BIOS password, CMOS RAM, or an encrypted USB port, and they do not offer the same level of security for preventing the hard drive from being used in another computer.
